The prescaler settings are not the same. Check the prescaler bits and you will find that the new timer have a more fine tuned prescaler. Bengt _____ Fr?n: icc-avr-bounces@imagecraft.com [mailto:icc-avr-bounces@imagecraft.com] F?r Dan Mullin Skickat: den 28 april 2009 15:56 Till: icc-avr@imagecraft.com ?mne: [Icc-avr] Timer0/Timer1 prescaler on ATMega-8 Guys, This may be a simple question but I am simply trying to resolve something on the ATMega-8 that is confusing me. The documentation indicates that Timer0 and Timer1 share a single prescaler. However, Figure 31 in the manual showing the clock fanout seems to show a prescaler outputting all of the possible clock rates and the CS00-CS02 bits and CS10-CS12 bits being used to select which of the prescaler outputs is actually used by each timer. In yesterdays project I had Timer 0 set up for a clk/256 prescale via TCCR0 CS00-CS02 to generate a generic time interrupt every 4ms. I also had Timer 1 set up for a clk/8 prescale via TCCR1B CS10-CS-12 to generate some PWM. The Timer 0 init code is executed before the Timer 1 init code. In a previous rev of this code the PWM section was not active and Timer 1 was not initialized. Timer 0 executed the 4ms interrupt rate just fine. However, now that I added the Timer 1 code and started running the PWM it appears that Timer 0 has also glommed onto the prescale 8 setting and has started interrupting 32 times faster! Being under a time crunch I simply init'ed Timer 2 to act as the 8-bit timer, moved the applicable code, and shipped the firmware. However, as I tend to use the bigger ATMega's with their mega timers and prescalers does anyone have any insight to share on what I may be missing in the ATMega-8?

You would normally use multiplexing - have a driver for each column of LED's, then enable each row one at a time and output the appropriate pixels on the columns. You can use a stack of 74HC595 serial/parallel latches to drive the 96 columns. The only trouble is this gives 1/8th brightness on the LEDs which you can get round to some extent by overdriving the LED's, as they only get short pulses. -- Tim Mitchell From bibi at microsyl.com Tue May 19 06:10:46 2009 From: bibi at microsyl.com (Sylvain Bissonnette) Date: Tue May 19 07:19:24 2009 Subject: [Icc-avr] LED matrix display design?

In-Reply-To: <200905191646.n4JGk6IL083433@mail.imagecraft.com> References: <200905191646.n4JGk6IL083433@mail.imagecraft.com> Message-ID: Large arrays of LEDs are best muiltiplexed so as to keep power dissipation down. However, the circuitry is more complex than simple individual LE#D drivers. Multiplexing organizes the array into a rectangle matrix of LEDs with row drivers and column drivers. The column drivers are typicalled open-drain or equivelant. Multiplexing works by quickly lighting LEDs for short period of time such that the entire matrix is lit at greater than 20Hz or so. During the short time an 'ON' LED is lit higher current is passed through it, which will result in higher instantaneous brightness for the short pulse duration. This works in practice because the higher peak brightness is sensed by the eye (visual persistence). A properly designed Multiplexed display can exhibit significantly lower average power dissipation than continuously fed LEDs or equivelant size. Some of the more advanced circuit designed limit the pulse width of applied current in hardware as to protect against LED burnout in case the multiplexing action is halted for some reason.

You would normally use multiplexing - have a driver for each column of LED's, then enable each row one at a time and output the appropriate pixels on the columns. You can use a stack of 74HC595 serial/parallel latches to drive the 96 columns. The only trouble is this gives 1/8th brightness on the LEDs which you can get round to some extent by overdriving the LED's, as they only get short pulses. -- Tim Mitchell ------------------------------ Message: 6 Date: Tue, 19 May 2009 09:10:46 -0400 From: Sylvain Bissonnette Subject: Re: [Icc-avr] LED matrix display design?

Typical cases are the format strings of cprintf() and implicite error messages of lib functions like ftoa(). There is no way to let map file summary find out those data, unless Richard can make them appear in .mp file somehow. Sorry.
